Textbook outcome following oesophagectomy for cancer: international cohort study

Background

Textbook outcome has been proposed as a tool for the assessment of oncological surgical care. However, an international assessment in patients undergoing oesophagectomy for oesophageal cancer has not been reported. This study aimed to assess textbook outcome in an international setting.

Methods

Patients undergoing curative resection for oesophageal cancer were identified from the international Oesophagogastric Anastomosis Audit (OGAA) from April 2018 to December 2018. Textbook outcome was defined as the percentage of patients who underwent a complete tumour resection with at least 15 lymph nodes in the resected specimen and an uneventful postoperative course, without hospital readmission. A multivariable binary logistic regression model was used to identify factors independently associated with textbook outcome, and results are presented as odds ratio (OR) and 95 per cent confidence intervals (95 per cent c.i.).

Results

Of 2159 patients with oesophageal cancer, 39.7 per cent achieved a textbook outcome. The outcome parameter ‘no major postoperative complication’ had the greatest negative impact on a textbook outcome for patients with oesophageal cancer, compared to other textbook outcome parameters. Multivariable analysis identified male gender and increasing Charlson comorbidity index with a significantly lower likelihood of textbook outcome. Presence of 24-hour on-call rota for oesophageal surgeons (OR 2.05, 95 per cent c.i. 1.30 to 3.22; P = 0.002) and radiology (OR 1.54, 95 per cent c.i. 1.05 to 2.24; P = 0.027), total minimally invasive oesophagectomies (OR 1.63, 95 per cent c.i. 1.27 to 2.08; P < 0.001), and chest anastomosis above azygous (OR 2.17, 95 per cent c.i. 1.58 to 2.98; P < 0.001) were independently associated with a significantly increased likelihood of textbook outcome.

Conclusion

Textbook outcome is achieved in less than 40 per cent of patients having oesophagectomy for cancer. Improvements in centralization, hospital resources, access to minimal access surgery, and adoption of newer techniques for improving lymph node yield could improve textbook outcome.

INFLUENCE OF THE DURATION OF DIABETES AND VIBRATION PERCEPTION THRESHOLD ON THE SEVERITY OF ERECTILE DYSFUNCTION IN PATIENTS WITH TYPE 2 DIABETES MELLITUS

BACKGROUND

Erectile dysfunction(ED) in men is a frequent under-reported complication of diabetes mellitus, which is becoming significant health problem worldwide.

AIMS

The study aims to determine the prevalence and risk factors for development of ED in North Indian patients with type 2 diabetes mellitus.

METHODS

We used international index of erectile function (IIEF-5) for the assessment of ED in 796 patients with type 2 diabetes mellitus. We recorded the age, duration of diabetes, glycemic status, body mass index, diabetes medications, microvascular and macrovascular complications.

RESULTS

The mean age of patients in the study was 49.38 ± 9.52 years. The prevalence of ED in patients with type 2 diabetes mellitus was 79.4%. Logistic regression analysis revealed that age, body mass index, glycemic control, insulin therapy, retinopathy and nephropathy was not significantly associated with erectile dysfunction in patients with type 2 diabetes mellitus. Duration of diabetes (OR = 1.054, 95% CI 1.007 to 1.102, P=0.023) and vibration perception threshold (OR = 1.071, 95% CI 1.042 to 1.102, P=0.000) were identified as key risk factors for development of ED.

CONCLUSION

Duration of diabetes and peripheral neuropathy emerged as significant risk factors for development of severe erectile dysfunction.

133 A Quality Improvement Project to Improve the Appropriateness of Acute Clinic Referrals to a Local ENT Department Using an Electronic Booking System

Aim

Assess and improve the proportion of inappropriate acute clinic referrals being made to our local ENT department via a telephone referral system with regards to nature and suitability for a junior grade doctor run clinic with senior supervision. Additionally, to make a more efficient, timely and failproof booking system with an auditable trail by transitioning to an electronic referral system.

Method

A guideline was created using based on common protocols from major Trusts within the UK which was then used to assess 101 acute clinic referrals taken from February 2021 to our local service. An electronic referral system was created, and guidelines disseminated to departments commonly making referrals to the acute clinic in anticipation for re-audit in September 2021 alongside introduction of the guideline to new doctors rotating to the specialty at induction in August.

Results

Initial audit revealed 29% of referrals were inappropriate, 50% of which were too complex, 45% were not acute and 5% were due to accidental double-bookings. Additionally, nasal fracture reviews were seen within 10 days only one third of the time, 37% of patients referred did not have a recorded contact number and 13.8% of all referrals were made with incorrect or unclear clinical information.

Conclusions

The lack of clear clinical guidance on referrals to an acute ENT service at our local centre with an outdated telephone referral system is associated with a large proportion of inappropriate referrals, delays to timely care and transcription errors potentially putting patients at risk of harm.

106 Laparoscopic Cholecystectomy Following an Episode of Cholecystitis: Are We Meeting the NICE Guidance?

Aim

On average, acute cholecystitis is responsible for 3% of admissions to emergency general surgery wards. NICE Guideline [QS104] states that adult patients admitted with acute cholecystitis should be offered a laparoscopic cholecystectomy within one week of diagnosis. This study aims to assess adherence to this guideline in a medium size district general hospital.

Method

Data was gathered retrospectively from contemporaneous electronic-based patient record system. Patients with a first case of cholecystitis within a 486-days’ time period were included; incorrect coding or repeat admissions within our time period were excluded. Data was gathered on admission length, aetiology, investigations undergone and procedure type (open vs laparoscopic). Additionally, for those that underwent a cholecystectomy, the length of time between diagnosis and operation was calculated.

Results

72 adults were admitted with acute cholecystitis in the 486-day study period. The median length of stay was 3 days. The commonest aetiology was either gallstones or unknown (47.2% of cases each), followed by bacterial infection (5.6%). 9 patients (12.5%) underwent laparoscopic cholecystectomy, and 10 (13.9%) were placed on a waiting list. The remaining 53 (73.6%) had no mention of being listed for surgery in their notes. Of those undergoing laparoscopic cholecystectomy (n = 9), none were within the recommended one-week period from time of diagnosis.

Conclusions

Over 486 days, no patients diagnosed with acute cholecystitis in our unit were being treated according to NICE guidance. We therefore recommend reinstating the hot gallbladder list at this hospital, which will enable surgeons to deliver the biliary emergency service advocated by the national guidelines.

107 Retrospective Pilot Study in Preparation for Setting Up an Acute Pancreatitis MDT in a Medium Sized NHS Acute Trust in the UK

Aim

Within the spectrum of pancreatitis, patients with severe disease require specialist multidisciplinary care including dietician and radiology input. Therefore, certain patients would benefit from an MDT approach to coordinate their management. This retrospective study analyses data on pancreatitis admissions within our Trust, to inform the set-up of a new specialist MDT.

Method

Patients were identified using admission coding data. Relevant patient data was extracted, including demographics, disease severity (using the Atlanta classification) and relevant outcomes. Both first-time and repeat admissions were included. Incorrectly coded patients were excluded. Statistical analysis was performed using SPSS (Version 23.0).

Results

Over a study period of 489 days, 246 patients were coded as having pancreatitis.186 patients were first time admissions, and 27 patients were repeat admissions. 33 patients were incorrectly coded and excluded.

Hence, the annual acute pancreatitis admission rate was 139 patients/year, with an additional 20 readmissions. 149 (80%) admissions were mild cases, with the remaining 14 (8%) and 23 (12%) being moderate and severe respectively. 149 (80%) were acute cases, compared to 20 (11%) chronic and 17 (9%) acute-on-chronic. 52/186 cases had no cause of pancreatitis recorded; where cause was identified, gallstones were the most common aetiology.

Conclusions

Pancreatitis is a common reason for admission during a general surgery on-call in our Trust; while the majority of cases are mild, the remaining 20% of moderate–severe cases qualify for discussion at an Acute Pancreatitis MDT. This pilot has facilitated the allocation of resources in our Trust and the MDT goes live in September 2021.

Utility of sonographic transcerebellar diameter in the assessment of gestational age in normal and intrauterine growth-retarded fetuses

Background

The fetal cerebellum has been shown to be least affected by external pressures and molding during pregnancy and therefore might provide more accurate estimation of GA.

Aims

To study the utility of transcerebellar diameter (TCD) measured by ultrasound for the detection of GA in normal and intrauterine growth-retarded (IUGR) fetuses.

Subjects and Methods

This cross-sectional study comprised 500 antenatal patients with a GA between 14 and 39 weeks and who were certain of their last menstrual periods. The TCD was measured ultrasonographically and the corresponding GA was determined. The GA was also determined with other customarily used sonographic parameters such as biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL) and compared with TCD. Data of normal pregnancy patients was used to formulate nomograms by taking the 5^th, 50^th, and 95^th percentile measurements. TCD to AC ratio was also calculated in both normal (n = 424) and IUGR pregnancies (n = 76).

Results

TCD showed significant correlation with gestational age (GA) measured by last menstrual period (LMP) as well as with GA calculated with other biometric fetal parameters. TCD also showed significant correlation with GA in normal (R² = 0.979) as well as with IUGR pregnancies (R² = 0.942). TCD to AC ratio remained fairly constant in normal pregnancies while it was increased in IUGR pregnancies.

Conclusions

TCD and TCD/AC ratio can be employed as an objective parameter to establish the GA in normal as well as IUGR pregnancy cases.

Intrauterine proteolytic enzymes therapy hastens expulsion of fetal membranes in dystocia affected buffaloes

Background

Difficult calving (dystocia) in buffalo cows is a major obstetrical problem which further leads to metritis complex, encompassing the retention of fetal membranes (RFM), puerperal metritis, endometritis and pyometra with impaired future fertility.

Aims

The current study aimed to evaluate the effect of the administration of intrauterine proteolytic enzymes on the expulsion of fetal membranes and postpartum fertility in dystociac buffaloes.

Methods

Proteolytic enzymes consisting of Trypsin (16 mg), Chymotrypsin (16 mg), and Papain (8 mg) were dissolved in 500 ml normal saline were administered after 1 h of assisted delivery in dystociac buffaloes along with the conventional therapy.

Results

The treated animals (n=15) expelled fetal membranes within a shorter period of time (P=0.043) compared to the control group (n=15) with none in the treatment group retaining it for more than 24 hours. Fewer (26.67 vs 73.33%; P=0.027) postpartum uterine infections developed in the treated animals compared to the control group. The interval between first postpartum estrus (P=0.067), service period (P=0.554), and open days (P=0.557) was shorter in the treatment group compared to the control group where postpartum anestrus developed less frequently (26.67 vs 66.67%; P=0.066) in the animals treated with enzymatic therapy. Systemic illness (neutrophillia) was reduced in the treatment group compared to the control on day 20 (64.55 ± 1.14% vs 70.23 ± 0.99%; P=0.001) and 45 (55.05 ± 1.63% vs 64.92 ± 1.45%; P<0.001) postpartum.

Conclusion

It is concluded that proteolytic enzymes therapy after assisted delivery in dystociac buffalo cows could help in the early expulsion of fetal membranes and reduce uterine infections with decreased neutrophils count.

Changes in surface morphology, lectin staining, and gene expression of caprine endometrium exposed to estradiol, progesterone, and mifepristone in vitro

BACKGROUND

In mammalian females, the uterine tissue is highly responsive to steroid hormones and their antagonists.

AIMS

In the present study, topographical, histoarchitectural, and gene expression changes in goat endometrium treated with estradiol, progesterone, and mifepristone for 24 h were investigated, in vitro.

METHODS

Scanning electron microscopy (SEM) was used for surface topographical analysis; WGA and DBA lectins were used for histochemical analysis; and qRT-PCR was done for the quantification of mRNA levels of MKI67 (marker of proliferation Ki67), ESR1 (estrogen receptor), PGR (progesterone receptor), CASP3 (caspase 3), and PDGFR-β (platelet derived growth factor receptor-β).

RESULTS

Few topographical alterations were observed in endometrial glands and the presence of scattered mucoid granules. A significant decline in WGA staining was reported only in the progesterone group. However, DBA binding was highest in the progesterone group and lowest in the mifepristone group. The expression of MKI67 gene declined to 79% in the mifepristone group, while in the estradiol and progesterone groups it elevated to 153% and 41%, respectively, than control; a similar trend was observed for PDGFR-β. The mRNA abundance for ESR1 declined to 59% in the progesterone group and 10% in the mifepristone group. However, a 100% increase occurred in the estradiol group. PGR expression followed the same trend as that of ESR1. CASP3 declined in the estradiol (50%) and progesterone (37%) group, but it showed a 67% increase in the mifepristone group.

CONCLUSION

We concluded that the caprine uterus undergoes dramatic alteration in structure and functions in response to different kinds of steroidal environments.

TB free India: Reaching the unreached tribal population under National Tuberculosis Elimination Programme

India is the highest TB burden country in the world. The burden however is not uniform in different strata including tribal population - one of the key affected populations in the country. As the evidences from tribal population are hardly available, most of the policies and strategies implemented under National Tuberculosis Elimination Programme (NTEP) are usually based on the evidences from general populations. NTEP is continuously taking steps to strengthen TB services in tribal areas. The Social Action Plan including Tribal Action Plan is in place and the appropriate strategies are incorporated in the National Strategic Plan (NSP) to ensure universal access to quality TB services to vulnerable population groups. However, its implementation becomes challenging especially in tribal areas as different tribal groups have their own unique ways of dealing with health issues. These issues are therefore required to be addressed holistically involving all the stakeholders. In view of this a symposium was jointly organized by the Central TB Division (CTD), Govt. of India and ICMR - National Institute of Research in Tribal Health (NIRTH), Jabalpur on 17th and 18th December, 2019 at ICMR - NIRTH, Jabalpur. It provided an excellent platform for all the stakeholders from different parts of the country to share their experiences in tuberculosis particularly among marginalized populations. The recommendations emerged out of this interactive symposium highlight the sincere effort of NTEP to tackle TB situation in tribal population and show the way forward towards India's TB elimination goal by 2025 especially in hard to reach tribal areas.

Intermolecular Nucleophilic Addition Reaction of a C-7 Anion from N-[Bis(dimethylamino)phosphoryl]indole to Electrophiles/Arynes: Synthesis of 7-Substituted Indoles

A novel approach to the C-7 substitution of N-[bis(dimethylamino)phosphoryl]indole by nucleophilic addition of the corresponding C-7 carbanion to electrophiles or arynes is described. The directing group can be easily removed, providing a simple route to the synthesis of 7-functionalized indoles.

Photophobia as a Presenting Feature in Adie's Tonic Pupil

A 34 years old female presented with complains of photophobia since 6-7 months. On examination, she had anisocoria of 4 mm in room light which increased in bright light. The left pupil was dilated and unresponsive to direct and indirect light stimuli. It did however, constrict slowly on near fixation followed by slow redilatation on distance fixation. A diagnosis of Adie's tonic pupil was made since left pupil constricted with instillation of dilute pilocarpine 0.1%. Her symptoms of photophobia and blurred vision immediately resolved. Photochromatic glasses and dilute pilocarpine 0.1% three times a day were prescribed. Prompt symptomatic relief of photophobia and blurred vision was observed.

Performance of prognostic scores in prediction of 30-day postoperative mortality in COVID-19 patients after emergency surgery: A retrospective cohort study

Background

: Risk assessment with prognostic scoring, though important, is scarcely studied in emergency surgical patients with COVID-19 infection.

Methods and Material

We conducted a retrospective cohort study on adult emergency surgical patients with COVID-19 infection in our institute from 1 May 2020 to 31 October 2021 to find the 30-day postoperative mortality and predictive accuracy of prognostic scores. We assessed the demographic data, prognostic risk scores (American Society of Anesthesiologists-Physical Classification (ASA-PS), Sequential Organ Failure Assessment (SOFA), Quick SOFA (qSOFA), Physiologic and Operative Severity Score for the enUmeration of Mortality and Morbidity (POSSUM) and Portsmouth-POSSUM (P-POSSUM) scores), surgical and anesthetic factors. We assessed the postoperative morbidity using the Clavien-Dindo scale and recorded the 30-day mortality. Correlation of prognostic scores and mortality was evaluated using Univariate Cox proportional hazards regression, receiver operating characteristic curve (ROC), Youden's index and Hosmer- Lemeshow goodness of fit model.

Results

Emergency surgery was performed in 67 COVID-19 patients with postoperative complication and 30-day mortality rate of 33% and 19%, respectively. A positive qSOFA and ASAPS IIIE/IVE had a 9.03- and 12.7-times higher risk of mortality compared to a negative qSOFA and ASA-PS IE/IIE (P &lt; 0.001), respectively. Every unit increase of SOFA, POSSUM and P-POSSUM scores was associated with a 50%, 18% and 17% higher risk of mortality, respectively. SOFA, POSSUM and P-POSSUM AUCROC curves showed good discrimination between survivors and non-survivors (AUC 0.8829, 0.85 and 0.86, respectively).

Conclusions

SOFA score has a higher sensitivity to predict 30-day postoperative mortality as compared to POSSUM and P-POSSUM. However, in absence of a control group of non-COVID-19 patients, actual risk attributable to COVID-19 infection could not be determined.
